Since her introduction in April of 1930, the Nancy Drew books have never been out of print.

Over the years the books have had new cover art and, from 1959 to 1977, the first 34 stories have been revised. The revisions eliminated obsolete prose and, in some cases, racial stereotypes that would today be considered offensive. The revised tales and stories published since 1959 have a more or less uniform length to lower publishing costs.

Revisions ranged from a light edit to a totally new story. Most Drew fans agree that the Original Text versions of the story are superior to their revised counterparts.

Grosset & Dunlap is the publisher for the original series and revisions. In a 1979 court decision, Grosset & Dunlap lost the right to publish new stories in the series to Simon & Schuster. G&D did, however, retain the right to continue publishing the first 56 tales (known as the "canon") and continues to publish them to this day.

From the Spring of 2005 until circa 2013, G&D had Simon & Schuster's permission to reprint the first 8 volumes of the Digests. These were published in the so-called "Flashlight" laminated picture cover binding using a modified version of the original Digest art.

Applewood Books published facsimile editions of the early, unrevised editions of the Nancy Drew volumes 1 through 21 from 1991 to 2005.

Nancy Drew Twin Thrillers

The 27 volume Twin Thriller book club editions, containing two stories in one volume, were issued in the 1970s. All were revised text (RT) except Volume 13, "The Mystery Of The Ivory Charm", which retained the original text (OT).
Only volumes 1-54 were issued in this set, with the books being slighter smaller in height than regular Drew PC editions. Taller editions (about 3/4") of volumes 1-16 were issued in a the same basic format.
It seems to me that the series was issued no later than 1978, before the publication of volume 56, "The Thirteenth Pearl" in 1979 and commenced before the revision of Volume 13, "The Mystery Of The Ivory Charm", in 1974. But that, of course, is just speculation.
Issued in picture cover (PC) format with lavender binding, they have a design on the spine & plain back cover with a small G&D book # on the lower right.
The cover features the then-current artwork of one of the titles in the book except volume one, which uses the art from the Nancy Drew Triple Edition.
